A 12-year-old girl is one of three more people confirmed with swine flu, Prime Minister Gordon Brown said today.

The girl, from Torbay in Devon, and adults from London and Birmingham were confirmed with the flu, he told the Commons.

The first two British cases were confirmed on Monday in Scotland.

All three new cases recently travelled to Mexico, the Prime Minister said.

They displayed mild symptoms and were responding well to treatment.

The girl's school, Paignton Community College, has been temporarily closed and all other pupils offered anti-viral treatment.

Mr Brown said the UK is taking ''the preparations that are necessary and the precautions to prevent the incidence of this disease in this country''.

Measures include enhanced airport checks, expanding anti-viral stocks from 35 million to 50 million, ordering extra face masks and printing an information leaflet for every family.
